WINDOW Application :led July 18, 1928.

This invention relates to improvements in windows and more particularlyto the type of windows having upper and lower sliding sashes.

The primary object of my invention is to provide a window structurehaving sashes that can be raised and lowered by the usual sash weightsand cords and -which may be turned on a horizontal aXis when broughtinto their eXtreme lowered position to facili tate the reversing of thesame to present both sides of the window pane for cleaning on theinside. c y

Another object of my invention is to provide awindow which does notnecessitate the climbing out on the window sill or sitting upon the sameto clean both sides of the pane o glass which has proven very dangeroust those who must perform this work.

Another Objectis to provide a window that has the; appearance of anordinary window but has upper and lower sashes which can be swung on ahorizontal axis without requiring the actuation of a number ofparts.

A still further object of my invention is to provide a window havingsashes that can be easily removed when it becomes necessary to take alarge object such as a safe, piano or the like through the window.

`With these and other objects in view, the invention resides in certainnovel constructionand combination and arrangement of parts, theessential features of which are hereinafter fully described, areparticularly pointed out in the appended claims, and are illustrated inthe accompanying drawing, in which Figure 1 is a perspective view of myimproved window showing the lower sash partly turned.

Figure 2 is a vertical sectional view taken on the line 2-2 of Figure 1.

Figure B is a vertical longitudinal sectional view taken on the line 3 3of Figure 2.

Figure 4 is a horizontal sectional view taken on the line 44-. of Figure2.

Figure 5 is a vertical sectional view similar to that of Figure 2 butshowing the lower sash raised and the upper sash lowered and swung onits horizontal axis.

Serial No. 293,551.

Figure 6 is a horizontal sectional view taken on the line 6 6 ot F igure2.

Figure 7 is asimilar View taken on the line A7 7 of Figure' 5.

Figure 8 is a detail perspective view of one 55 of the sash members withone of the locking bars 1n a drawn out position.

Figure 9 is a detail perspective view of a part. of the frame showingthe slots in the parting strips.

Referring to the drawings by reference characters, the numeral 10designates my improved window in its entirety which includes a iframestructure 11 embodying a sill 12, and having sets of spaced partingstrips 13 and 65 14 attached to the inner vertical sides thereof, whichprovide grooves 15 and 16 therebetween, to slidably receive pairs oflocking bars 17 and 18 respectively, which pivotally support upper andlower sashes 19 and 20. 70

Frovided in the inner sides of the parting strips are upper and lowerlongitudinal slots 21 and 22 respectively, having offset portions 23 and211 at their lower ends, while the upper ends of the same open onto theside 'faces of 75 the strips as at 25 and 26 to permit lsets of guidepins 27 and 28, which extend from the sides of the locking bars 17 and18 to be inserted into their respective slots.

'l he upper and lower sashes 19 and 2O are provided with recesses 29 and30 along the side rails thereof which slidably receive the locking bars17 and 18 when in locked sliding position, to allow the sashes to beraised and lowered on a vertical plane under normal conditions.

Hingedly mounted as at 31 to the sill 12 is a sash stop 32 which undernormal conditions lies in thedownward path of the sashes to prevent theguide pins, carriedby the locking bars, from entering the offsetportions 23 and 24 of their respective slots.

For pivotally .supporting the upper and lower sashes in their respectiveopposed sets of sliding bars 17 and 18,1 provide ivot pins 95 33 and '34which have their outer en s threaded into the side bars and their otherends free within openings 35v and 86 in the side rails ot the respectivesashes. By iixedly securing the pivot pins to the slide bars and leav-100 2 message ing them free with the sashes, the slide hars may he movedto extended positions beyond the side rails of the sashes to releasethem :tor swinging movement in a manner to he hereinafter fullydescribed.

For supporting the sashes in their various adjusted sliding positions, lemploy the usual sash cords 37 which have one of their ends connected tothe upper ends ot the slide hars of the respective sashes, while weights38 are carried by their other ends, the sash cords being trained overpulleys 39 journalled at the top of the frame.

From the description, it can he readilyv understood that when it isdesired to clean the panes of either the upper or lower sashes on bothsides, the lower sash 2O must he raised a distance, tar enough, to allowthe sash stop 32 to he swung out of the downward path of the sashes andinto the position as shown in full lines in Figures and 2 of thedrawing. Assume that it is desired to clean the pane of the lower sash,whereupon the lower sash 20 is dropped to its lowermost position atwhich time the bars 18 slide out ot the recesses 30 in the side rails ofthe sash and into the grooves 16, as the guide pins 29 ride into theotset portions 24- of the slots 2Q. The lock hars i8 are now clear ofthe side rails of the lower sash and the same is tree to he swung on itshorizontal pivot pins Se. fitter the pane of the lower sash has beencleaned on hoth sides, the same is swung haal; to'normal verticalposition so that the recesses 30 register with the grooves lf3 and asthe sash is raised the guide pins ride out or" the offset portion, haeltinto the slots 22 which cause the slide hars. to los moved nto lool;-ing engagement with. the side As ot the lower sash.

T he lower sash is most position to allo he brought to its loW the partsof the u onstruction as the 1 same manner as f is not hef STU.
